Guidelines for fire safety of battery energy storage systems to support the transition to a fossil fuel free society

There are currently no rules, advice or standards for how fire protection for battery energy storage systems should be dimensioned or where battery energy storage systems can be installed in Sweden. This creates an uncertainty for those who want to install battery energy storage systems.

As there are no national instructions, it is the rescue service in the municipality where the energy storage is installed, that decides what requirements are to be set.

This results in different requirements in different municipalities and leads to more expensive installations, which risks a fast transition towards a fossil-free future.The aim of this project is to produce national guidelines, regarding dimensioning and fire safety requirements for battery energy storage systems, to facilitate and support the transition for a fossil-free society.

The guidelines will be based on existing research and knowledge regarding battery energy storage and lithium-ion batteries, as well as through knowledge exchange with the rescue services and installers/manufacturers of battery energy storage systems as well as with other stakeholders.
